SunRunner™ System Cores

The System Core is what takes power from the roof mounted combiner box and feeds it into your battery bank. The essential components of a System Core include a wire harness, charge controller and fuse kit. More elaborate System Cores include monitoring kits and disconnects.

The name of each SunRunner System consists of a number representing the maximum current rating, "PWM" or "MPPT" referencing the type of charge controller used, and a forward slash followed by a number representing the wire gauge. Therefore, a SunRunner 30PWM/10 system uses a 30 amp PWM charge controller with a system wiring harness that uses 10 gauge cable between the roof combiner box and the controller and also between the controller and the batteries. Likewise, a SunRunner 40MPPT/4 would be based on a 40 amp MPPT controller that uses 4 gauge cable for increased efficiency and lower voltage drop at higher currents.

Our SunRunner System designs are the result of 29 years of hands-on experience gained from selling, installing and living with these systems. We are constantly improving our designs and component offerings based on customer feedback and personal experience. If we can't find products to meet our needs, we task ourselves to build (or have built) a product to our specifications. Because of that, our systems are unique in the field. We have thousands of satisfied customers who are living, loving and playing in their RVs which are powered by AM Solar SunRunner Systems.

It can regulate up to 400 watts of solar panels and is compatible with our roof mounted combiner boxes. Thick 6 gauge wire reduces lines losses for optimum efficiency.

This kit is built around an MPPT charge controller and offers a digital display, system programming, battery monitoring, temperature compensation, disconnects and cable management hardware. It can regulate up to 640 watts of solar panels and is compatible with our roof mounted combiner boxes. Thick 4 gauge wire reduces lines losses for optimum efficiency.

This kit is built around a Victron Blue Solar MPPT 100|15 charge controller and does not come with any monitoring equipment, but is compatible with several optional add-on monitoring kits. It can regulate up to 200 watts of solar panels in optimal conditions (more in higher latitudes) and is compatible with our roof mounted combiner boxes. 8 gauge wire reduces lines losses for optimum efficiency. This system core is the preferred choice for our lithium battery systems, but it is also fully compatible with lead-acid battery banks.

This kit is built around a Victron Blue Solar MPPT 100|30 charge controller and does not come with any monitoring equipment, but is compatible with several optional add-on monitoring kits. It can regulate up to 400 watts of solar panels in optimal conditions (more in higher latitudes) and is compatible with our roof mounted combiner boxes. Thick 6 gauge wire reduces lines losses for optimum efficiency. This system core is the preferred choice for our lithium battery systems, but it is also fully compatible with lead-acid battery banks.

This kit is built around a Victron Blue Solar MPPT 100|50 charge controller and does not come with any monitoring equipment, but is compatible with several optional add-on monitoring kits. It can regulate up to 670 watts of solar panels in optimal conditions (more in higher latitudes) and is compatible with our roof mounted combiner boxes. Thick 4 gauge wire reduces lines losses for optimum efficiency. This system core is the preferred choice for our lithium battery systems, but it is also fully compatible with lead-acid battery banks.

This kit is built around a Victron Blue Solar MPPT 100|70 charge controller and does not come with any monitoring equipment, but is compatible with several optional add-on monitoring kits. It can regulate up to 940 watts of solar panels in optimal conditions (more in higher latitudes) and is compatible with our roof mounted combiner boxes. Thick 2 gauge wire reduces lines losses for optimum efficiency. This system core is the preferred choice for our lithium battery systems, but it is also fully compatible with lead-acid battery banks.
